Finally, I did put most of my visualization tool demos online, which are linked from the talk itself. (These are visualizations I threw together in D3 to make it easier to interpret the output of my machine learning and stats analysis, since I was dealing with long text -- I needed to be able to browse the results and see the text on demand, too.)

I'll update this post with those links too, later, and maybe say a few words about my process, too. I'll be giving another talk specifically on visualizing LDA Topic Analysis in July at PyData Boston, building from some of this work.
